MP4 Problem Hello. I have a friends MP4, which they asked me to recharge battery on my computer. I managed to get it charged but somehow managed to erase the songs that were on it. I am trying to load them back on to the MP4 but WMPlayer tells me that there is a problem that the disk might be full, or it does not allow folders in it. THat WM cannot synchronize at this time. I really don't understand this thing. Maybe you guys can help me out. Thanks

Good morning, afternoon, evening or night; whatever time of day you are viewing this. Thank you for choosing FixYa to solve your problem. Your problem is that your MP4 player will not come on, even when you connect it to your PC? Well, you should try recharging your battery. There are two ways you can charge this device using your USB cable. The first way is by connecting the USB cable to your PC. Charging will take 8 hours by this method. The second way is connecting the USB cable to the wall charger that was supplied with your media player. If you had a problem connecting to your PC, you should try charging via the wall charger. Charging is much faster this way than using a computer. If charging doesn't turn your device back on, your battery may be defective. If that's the case, you'll need to get the battery or your media player replaced. Hope it's just a recharge that's needed. Thank you for choosing FixYa as your one-stop solution spot for your problems. Have a good day, afternoon, evening or night; whatever time of day you are viewing this.

Your MP4 driver disk must be installed and run BEFORE you hookup the MP4 player.If you have done the faux pas above, all the installs in the world will not fix it. You MUST remove the USB driver. Use Device Manager. In XP, this is found by right clicking my computer and selecting properties. In properties select the hardware tab and choose 'Device Manager'.

Stop here. If you have no idea what I wrote, review 'Device Manager' on the Windows Website or ask a KNOWLEDGEABLE friend for help. See http://support.microsoft.com/kb/310123.

Now, select the MP4 device, while it is plugged in to the USB port, and right click. Select 'Uninstall'. Remove your MP4 device when device manager is done.

Close Device manager and all the other windows. Start your USB install from scratch, without the USB plugged in untill the install asks or completes.I have ALWAYS had successful installs with this method.

The GPX ML759B has a Lion-Polymer rechargeable battery which does wear out pretty quickly especially when playing MP4 Videos. If your unit is 18months, you have done well!
If you have tried charging charging your player in a couple manners as stated, and you are happy that the charging system is working, then I strongly suspect that you will need to replace the internal LiOn-Polymer battery (whcih usually have a max life of 500 charges).
If you cannot replace the internal battery yourself, you may find that it may not be an economical option for a relatively cheap MP4 player.

MP3 or MP4 player encounter "Drive inaccessible or corrupted and unreadable" are likely defective.To be careful on it this mp4 player is memory damaged already.I tell you, you can no longer use this one anymore because i have a lot of mp3 or mp4 with the same problems you have, i try to repair & open it and check the circuit, even the integrated circuit can no longer use.I wanna say you a new one and don't wait this mp3 or mp4 player of yours are working back normally. Even I wanted to share to you about my knowledge on this but anybody would say "just buy a new one".Hope this tip might help you my friend.Good luck!Please rate me.Thank you.

Computer companies like to sell you expensive batteries. You must always remove your battery while you are plugged in, or you will greatly reduce its lifetime of about 300 or so full charges. Also, to break a new battery in properly, charge it for at least 15 hours, then let it completely drain and recharge 3 times.

Now, however, it sounds like your computer's charging settings are messed up. Go to device manager, open batteries, open microsoft AC adapter, see if it says that it is working properly. perhaps it somehow got turned off, or the files are corrupted. if all ok, open the microsoft ACPI-compliant control method battery--if that is what is in your laptop--otherwise check whatever else you have. If nothing appears wrong, update or replace the drivers from Toshiba's website. let me know how it goes.

If you got a USB cable with the unit, you can connect to your PC and recharge the battery that way. Just be sure to have the power switch turned ON. The screen on the player will indicate its connected and you should see the battery indicator in the lower right corner showing a charging condition (bar moving)
